1984 P30 454 Shredding Alternator Belt
As some of you may recall, I put a GM Performance crate 454 in my Allegro (I bought the rig with a blown engine). I swapped over the brackets and pulleys from the blown engine to the "new" engine. The...

I had the flex issue on my 79 chevy c30 truck with a 454. Before that I had the same rust issue with the pulleys. I replaced them all with aluminum ones and then noticed the flexing issue. I had heard that the napa belts, autozone belts and drive rite belts don't have as many threaded layers which causes the belts to be more elastic and stretch while in use, causing them to flex more, especially those belts with teeth on the inside. Dayco belts have more thread layers, with no inside teeth and don't flex as much because they don't stretch as much while in use. And it just about stopped the flex issue on my truck.
I made a custom bracket to install the same style chevy 12si alternator onto my 72 VW beetle. There was only one spot in that tight engine compartment to put it and had horrible flex with a drive rite belt to the point it kept throwing the belt off. Switched to a Dayco and the problem went away.
I do like the mid mount bracket tho, I didn't even know that existed. Might do that on my truck someday, but i won't do it on my RV as having the alternator higher up makes it a lot easier to change on my pace arrow. If it was as low as the mid mount, I wouldn't be able to get to it without removing the entire engine cover which would be a huge pain, especially If it went out during a trip. I keep my old alternator with a new pulley in my parts compartment where I store emergency oil, antifreeze, extra cap/ rotor, etc.
